SASH-CORD CLAMP.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed April 5, 1906. Serial No. 310,132.

To all whmn it may concern:

Be it known that LEVI W. STRAsBAUen, deceased, late a citizen of theUnited States of America, residing at York, in the county of York andState of Pennsylvania, did invent new and useful Improvements in Cord-Clamps, of which the following is a specification.

The invention relates to an improvement in rope-clamps designedprimarily for securing the sash-cords to the sash-stiles.

The main object of the present invention is the production of a clampdesigned for removable connection with the sash-stile and adapted whenin operative position to securely fix the sash-cord relative to thesash, the construction permitting the ready separation of the parts todisengage the rope and the convenient removal of the clamp as a wholeform the stile.

The invention will be described in the following specification,reference being had perticularly to the accompanying drawings, in whichFigure 1 is a longitudinal section of a portion of a window-stile,illustrating the application of the improved clamp thereto. Fig. 2 is afront elevation of the same. Fig. 3 is a perspective detail of the clampproper, the parts being shown separated. Fig. 4 is an end elevation of amodified form of barrel.

Referring to the drawings, the improved cord-clamp comprises a barrel 1and a lever 2, arranged for pivotal and removable connection with thebarrel. The barrel, which is cylindrical in sectional view, is formedwith a diametrically-arranged channel 3, herein after termed therope-channel, which opens through the upper end of the barrel andterminates above the lower end thereof in a rounded wall 4, forming therope seat. Horizontally-arranged grooves 5 are formed in transversealinement in the respective side walls of the channel 3, said groovesbeing ar' ranged near the upper end of the channel and opening throughthe rearedge of the channelwalls, the forward ends of the grooves terminating about centrally of the channel walls.

The lever 2 comprises a handle portion 6, which may be of thelength'desired and which is approximately of a width equal to the widthof the channel 3. The rear end of the handle is provided with anapproximately 1 V-shaped cam 7, offset from the plane of the handle, theapex of the cam being slightly rounded, as at 8, and forming ther0pegripping edge. The extreme rear end of the lever is formed withoppositely-disposed trunnions or bearing-studs 9, of a size to fitwithin the groove 5 of the barrel, whereby to provide the removablepivotal support for the lever.

It is to be understood that the improved rope-clamp above described isdesigned for application to the stiles 10 of the windowframe and thatits application and proper use will not necessitate the slightest changein the stiles as ordinarily constructed. The usual cord connection forwindow-frames necessitates the formation of a knot in the end of thecord, which is secured in a circular depression 11, formed in the stileby any suitable fastening means, such as a nail or the like, the stilebeing further provided with a grooveway, 12 extending longitudinally ofthe stile and in communication with the depression 11 to receive thecord, all of which is of the usual standard construction.

The improved clamp is designed for application to this standard type ofstile without the slightest change in the stile, the barrel 1 beingarranged to fit snugly within the depression 11, while the handleportion 6v of the cam-lever fits within the grooveway 12.

In use the sash-cord 13 is passed through the channel 3 in the barrelbelow the lever, it being understood that the lever has been previouslyconnected with the barrel and turned so as to elevate theoperating-point 8. After insertion of the cord the lever is turned downto cause the point 8 to bite into the cord and securely clamp the samebetween said lever and the wall 4 of the channel. The device may beinserted in the depression 11 either after the clamping of the cordtherein or after the insertion of the cord in the barrelchannel andprevious to the clamping operation of the lever.

It wiil be noted that the grooves 5 open toward the rear of the barreland that when said barrel is in place in the depression 11 the wall ofsaid depression closes the ends of said grooves, thereby preventing theaccidental displacement of the lever.

The free or forward end of the handle 6 of the lever rests upon thesash-cord in the grooveway 12, so that a lateral pull upon said cordwill elevate the free end of the lever relative to the barrel, andthereby disconnect said lever from the cord, permitting the readyseparation of the cord in a convenient and expeditious manner. Therelative size of the parts is such that the vertical extent of thebarrel is approximately equal to the depth of the depression 11, whilethe thickness of the lever is such as to avoid projection above thebarrel or grooveway 12 when the parts are in operative position.

If desired, the grooveway 12 may be extended beyond the depression 11,as at 14, whereby to permit the end of the sash-cord to be passed whollythrough the barrel and seated in said extension, whereby the cord itselfWill to some degree tend to prevent .acpidental disconnection of thebarrel and sti e.

In Fig. 4 is illustrated a slightly-modified form in that the side wallsof the channel 3 near their upper free edges are inclined slightlyoutwardly and upwardly, the

coacting portion of the lever being arranged to slightly spread thesewalls in forcing the lever to clamping position. As the barrel fitssnugly within the depression 11 within the stile, the slight spreadingof the walls incident to this construction provides for clamping thebarrel within the depression whereby to prevent possibility ofaccidental separation.

The salient features of the present invention are a rope-clamp,constructed of but two parts, each of which may be made at a singleoperation, a rope-clamp particularly designed and adapted forcooperation with the standard windowstile, requiring absolutely novariation or change in the ordinary form of stile, and a rope-clampwhich may be readily operated to release the rope by a slight lateralpull on the rope, whereby to provide for shortening or lengthening therope or its replacement by a new rope with the minimum loss of time andlabor.

Having thus described the invention,what is claimed as new is 1. Acord-clamp comprising a cord-receiving member designed for cooperationwith a window-stile, and means for clamping the sash-cord in saidmember, said means being arranged to be disengaged from the cord by apull on the cord in a direction approximately parallel to the face ofthe stile.

2. 'A cord-clamp designed for cooperation with a window-stile, and alever arranged to clamp the cord therein, said lever overlying the cordbeyond the clamp, whereby the lever is moved to inoperative position bya pull on the cord in a direction approximately parallel to the face ofthe stile.

3. A sash-cord clamp comprising a barrel adapted to fit within the usualdepression in the sash-stile and formed with a rope-receiving channel,and a lever removably and pivotally connected to the barrel andoperative to clamp the sash-cord within the channel.

4. A sash-cord clamp comprising a barrel formed with a cord-channel, thewalls of the channel being formed with transverselyalinedhorizontally-extending grooves, and a lever provided with a cam end andwith bearing-studs to fit in said grooves, the cam end of the levercooperating with the base of the cord-channel.

In testimony whereof I affix my signature in the presence of twowitnesses.
